CHECK-ROW` ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 223,821, dated JanuaryD27, 1880.

Application filed .T une 13, 187e.. i

To all whom t may' concern:

Be it known that I, JosErn STATLER, of Mason O ity, in the county ofMason and State of Illinois, have invented certain new and usefulImprovements in Check-Row Attachments for Corn-Planters; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to an improved checkrow attachment forcorn-planters; and it cony sists in a means for operating the slide, ofthe employment of a lock, and in the construction and combination ofparts, as will be hereinafter more fully set forth.

In the annexed drawings, which fully illustrate my invention, Figures 1and 2 are side elevations, and Fig. 3 is a plan view.

Like letters of reference indicate like parts.

A represents the slide, supported upon a frame, B, by means of straps a,-the said straps a a inclosing the ends of the slide and allowing thesame to pass back and forth through them.

The center of the slide A'is cut away, and in said cut-away portion,upon either side, in opposite corners, are placed the double-curvedblocks b b.

Secured to the frame B, by means of suitable straps c c, is a journal,O, having rigidly attached thereto a sprocket-wheel, D, working withinthe frame B, and the cams d d extending out to one side of the frame andworking in the cut-away portion in the slide A. The said cams d d areprovided with slots in their ends, in which are placed thefriction-rollers c e, which, when the cams are revolved, engage with thedouble-curved blocks b and give the slide the desired motion. The camsare placed one upon the other and crossed in the manner shown, so thatthe' inner cam engages with the block in the lower corner of the cutawayportion and moves the slide to the left, and the outer cam engages withthe block in the upper opposite corner and moves the slide in anopposite direction.

E E represent standards secured to the frame B, and extending upwardtherefrom. The upper portion of said standards are slotted, and in saidslotted portions are placed the pulleys ff.

F F represent the locks, pivoted in the frame B and having their lowerends secured together loy-means of the pivoted bar Ig. The upperportions of said locks are provided with slots h h.

This device is designed to be operated by means of a knotted wire orrope. The said wire or rope has a relative movement across the plantereither way, passing under the pulleys f and catching in the forks of thewheel D and the slots h in the ends of the lock. The wheel is movedone-fourth ofarevolut-ion, moving the sliding bar by means of the camsworking in one-fourth of a circle, the slide-bar being connected to .theslide-bar of the planter by means of a lever.

The operation of the lock is as follows: As the knot strikes the slot hin thelock it moves back at the top, so as to allow the wire or rope tostrike in the fork ofthe sprocket-wheel and move the wheel one-fourth ofa revolution, and as the next arm on the wheel passes `around it throwsthe lock again into position and locks the wheel until again released bythe wire or rope. By the arrangement of the lock it can be operated fromeither side.

By this arrangement a device is produced which operates with a greatreduction of friction, and one that is notliable to get out of repalr.

Having thus fully described my invention, what I claim as new, anddesireto secure by Letters Patent, is-

'In a check-row attachment for corn-plan ters, the sprocket-wheel D,locks F F, attached to each other by the double-pivoted bar g, standardsE E, and frame B, in combination with the cams d d, havingfriction-rollers e e, the sliding bar A, and` double-curved blocks b,all operated by mea-ns ot' a knotted wire or rope, substantially as andfor the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JOSEPH STATLER.
